The Keswick to Barrow (K2B) Walk is an iconic endurance challenge that runs through the heart of the scenic English Lake District. Covering 39.5 miles on foot, teams of 4 to 12 walkers and runners push themselves beyond their comfort zones, united by a shared goal: to raise vital funds for charities and good causes.

This is a fully supported event, with official timing checkpoints and regular support stations along the route providing food, drinks, first aid and encouragement when it’s needed most.

From elite runners who complete the course in just over 4 hours to walkers who cross the finish line after 8-12 hours, K2B is a test of determination, teamwork and resilience. Every finisher receives a completion certificate, and the pride of having taken on one of the UK’s most memorable challenge events.

Fancy taking on this team challenge to fight mitochondrial disease in one of the most beautiful spots in the UK?
